[Icom] IC756 and Yaesu Quadra amp - Band Data Interface design?

[Jerry Flanders]

I am getting a Yaesu Quadra amp to use with my IC-756PRO exciter. I know 
they can be used together, and lots of guys are doing so. BUT - I have not 
heard of anyone making up a band data interface to go between them to set 
the quadra to the band the PRO is on automatically. It appears that most of 
the guys let the quadra count the freq to set it up, and others set the 
quadra manually.

It appears that a LM3914 in dot mode and a set of diodes in a matrix is 
most of what is needed for a true band-data interface. Has anyone tried to 
set this up?
